Pima County AZ septic records are held locally, and we hold a parcel-matched copy of the recorded set: 137,977 scanned septic documents tied to 27,914 individual parcels as of September 2026. This page covers what is in that holding, what a septic as-built shows, and how to pull the record for a specific property.
As of September 2026 our corpus holds 137,977 recorded septic documents for Pima County, Arizona, matched to 27,914 individual parcels, about 4.9 documents per parcel. Pima County files run deep: the recorded set works out to roughly five documents per parcel, because a single system often carries a plan, a permit, and multiple inspection pages. These are the recorded documents themselves, as-builts, permits, and inspection records, pulled from public sources, tied to parcels, and viewable on the parcel map.
Pima County publishes septic plans through the county's public document access system, and a targeted query there reaches the scanned septic plan set directly. Our access page for the county records the query path we verified. The full access facts, custodian, records system, and whether anonymous search worked when we tested it, are on the county access page: Pima County septic records access.
The most useful document in the set is the as-built: the drawing filed when the system was installed or repaired. A typical as-built shows the tank location and size, the drainfield layout and dimensions, the reserve area, setbacks from wells, water lines, and property lines, and often the soil log from the original site evaluation. It is the document a buyer, an inspector, or a pumper actually wants. Our guide to reading a septic as-built walks through each element.
Plenty of older systems predate consistent filing. For those, our generator produces a free estimated design from code tables and nearby recorded systems. It is estimated, NOT a county-stamped document.
The county access page states where Pima County records are kept. The parcel map shows the documents tied to a specific property.
